These are more pretty-printers for generic ASN.1 structures. They're never
called externally and otherwise are only used in the X509V3_EXT_PARSE_UNKNOWN
mode for the X509 pretty-print functions. That makes unknown extensions
pretty-print as ASN.1 structures.
This is a rather useless feature, so have that fall through to
X509V3_EXT_DUMP_UNKNOWN which does a hexdump instead.

Many of the compatibility issues are described at
https://msdn.microsoft.com/en-us/library/mt612856.aspx. The macros
that suppressed warnings on a per-function basis no longer work in
Update 1, so replace them with #pragmas. Update 1 warns when |size_t|
arguments to |printf| are casted, so stop doing that casting.
Unfortunately, this requires an ugly hack to continue working in
MSVC 2013 as MSVC 2013 doesn't support "%zu". Finally, Update 1 has new
warnings, some of which need to be suppressed.
---
Updated by davidben to give up on suppressing warnings in crypto/x509 and
crypto/x509v3 as those directories aren't changed much from upstream. In each
of these cases, upstream opted just blindly initialize the variable, so do the
same. Also switch C4265 to level 4, per Microsoft's recommendation and work
around a bug in limits.h that happens to get fixed by Google include order
style.
(limits.h is sensitive to whether corecrt.h, pulled in by stddef.h and some
other headers, is included before it. The reason it affected just one file is
we often put the file's header first, which means base.h is pulling in
stddef.h. Relying on this is ugly, but it's no worse than what everything else
is doing and this doesn't seem worth making something as tame as limits.h so
messy to use.)

I messed up a few of these.
ASN1_R_UNSUPPORTED_ALGORITHM doesn't exist. X509_R_UNSUPPORTED_ALGORITHM does
exist as part of X509_PUBKEY_set, but the SPKI parser doesn't emit this. (I
don't mind the legacy code having really weird errors, but since EVP is now
limited to things we like, let's try to keep that clean.) To avoid churn in
Conscrypt, we'll keep defining X509_R_UNSUPPORTED_ALGORITHM, but not actually
do anything with it anymore. Conscrypt was already aware of
EVP_R_UNSUPPORTED_ALGORITHM, so this should be fine. (I don't expect
EVP_R_UNSUPPORTED_ALGORITHM to go away. The SPKI parsers we like live in EVP
now.)
A few other ASN1_R_* values didn't quite match upstream, so make those match
again. Finally, I got some of the rsa_pss.c values wrong. Each of those
corresponds to an (overly specific) RSA_R_* value in upstream. However, those
were gone in BoringSSL since even the initial commit. We placed the RSA <-> EVP
glue in crypto/evp (so crypto/rsa wouldn't depend on crypto/evp) while upstream
placed them in crypto/rsa.
Since no one seemed to notice the loss of RSA_R_INVALID_SALT_LENGTH, let's undo
all the cross-module errors inserted in crypto/rsa. Instead, since that kind of
specificity is not useful, funnel it all into X509_R_INVALID_PSS_PARAMETERS
(formerly EVP_R_INVALID_PSS_PARAMETERS, formerly RSA_R_INVALID_PSS_PARAMETERS).
Reset the error codes for all affected modules.
(That our error code story means error codes are not stable across this kind of
refactoring is kind of a problem. Hopefully this will be the last of it.)

Caught by malloc valgrind tests on Basic-Client-Sync. Also one by inspection
and verified with valgrind. Those should pass now with the exception of
CRYPTO_free_ex_data being internally implemented with malloc.
(Clearly we next should make our malloc tests assert that the containing
function fails to catch when we fail to check for some error and things
silently move one.)

Some files in crypto/x509 were moved from crypto/asn1, so they emit errors from
another module. Fix make_errors.go to account for this: cross module errors
must use the foreign module as the first argument to OPENSSL_PUT_ERROR. Both
the function code and the error code should be declared in the foreign module.
Update make_errors.go to ignore cross-module error lines when deciding which
function tokens to emit.

Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.
This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.
This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.
This removes support for externally-supplied error string data.

Including string.h in base.h causes any file that includes a BoringSSL
header to include string.h. Generally this wouldn't be a problem,
although string.h might slow down the compile if it wasn't otherwise
needed. However, it also causes problems for ipsec-tools in Android
because OpenSSL didn't have this behaviour.
This change removes string.h from base.h and, instead, adds it to each
.c file that requires it.
